Synthesis and Ab Initio Determination Bi1.256 La0.53 N0.231 O0.521 Zr1.543 Triclinic Structure from Powder X-Ray Diffraction Data

“…The differences in ionic radii ofBi, La and Zr ions also appear to influence the tilt and distortion of the ZrO3 - [11] in all these three structures, which indicate a measure of the extent of disorder in these phases. It also compares the tendency of the three oxides to incorporate A type cations in the [Bi2O2] layer and the perovskite layers [12].…”

Evaluation of the microstructure, optical properties and hopping conduction mechanism of rare earth doped Ba0.85Ca0.12RE0.03Ti0.90Zr0.04Nb0.042O3 ceramics (RE = Ce3+ and Pr3+)

“…6,7 These transitions are rhombohedralorthorhombic-tetragonal-cubic and hexagonal (R-O-T-C-H) at À90 C, 6 C, 130 C and 1432 C, respectively, associated with the off-centering of the Ti cation. 6 In effect, a relevant change in the behavior of the BT compound may be achieved via the incorporation or substitution of other ions in the Ti-and/or Basites. [4][5][6] Concerning the optoelectronic applications, rare earth ions (Ln 3+ ) are useful substituted ions to enhance the functionality of BT.…”

“…Perovskites with an ABO 3 general formula have gained a lot of interest over the past decades based on their potential applications and power in a variety of nanotechnology fields such as ferroelectric sensors, ceramic capacitors, optoelectronic devices, piezoelectric devices and actuators. 1–5 Among these materials, BaTiO 3 (BT) is the most frequently used as a typical dielectric compound especially due to the elevated permittivity resulting from the interaction between dielectric behavior 2,4–6 and structural deformation by means of Structural Phase Transitions (SPTs). 6,7 These transitions are rhombohedral–orthorhombic–tetragonal–cubic and hexagonal (R–O–T–C–H) at −90 °C, 6 °C, 130 °C and 1432 °C, respectively, associated with the off-centering of the Ti cation.…”
